There is still a debate whether primary lateral sclerosis (PLS) is a distinct pathological entity or whether it represents one end of a continuous spectrum of motor neuron disease (MND). In this report we present four PLS patients who have been observed from the time of symptom onset (1990-1999) through January 2007. All of them have had only upper motor neuron (UMN) signs and slow clinical progression. Three patients have been presented with spastic paraparesis. Spasticity was the main clinical feature in demonstrated cases with hyperactive deep tendon reflexes, clonus, and Babinski signs. One patient was presented with spastic dysarthria at the disease onset. Mean disease duration, measured from symptom onset to the present, was 11.5 years in our reported series. All four PLS patients had not developed lower motor neuron (LMN) signs during this time of observation. This prospective analysis of our PLS series is in agreement with data from other studies suggesting that pure PLS cases have a Motor Neurone Disease (MND) is one of the commonest neurodegenerative disorders of adulthood. MND characteristically presents with a combination of both upper and lower motor neurone features. Primary Lateral Sclerosis (PLS) is thought to be a variant of MND presenting with purely upper motor neurone signs. Debate continues over whether PLS constitutes a distinct pathological entity or whether it is part of the spectrum of motor neurone diseases that present as an upper motor neurone-predominant form of MND. We present a case of MND with purely upper motor neurone features and a prominent pain component. A pre-mortem diagnosis of PLS was made, however autopsy findings demonstrated both upper and lower motor neurone involvement. We believe these findings support the view that PLS is not a discrete pathological entity, but that it is a part of the range of motor neurone diseases that present with predominant but not exclusive upper motor neurone involvement. This case also highlights the feature that pain may be associated with MND even though it is not appreciated to have a sensory pathology.
this was taken from pub med/see my thread pls info, i have somewhere but can't find a article which states minor/non progressive lmn involvement can be had in pls
i'll try to find more
